Application filed October 30, 1916. Serial No. 128,521.

T0 all whom t may concern: Y

Be it known that I, FRANCIS R. HARDIE, a citizen of the United States, residing at SaltLake City, Salt Lake county, State of Utah, have invented a new and useful Attachment for Concentrators, which consists of certain new and useful attachments which may be fastened on and operated by concentrat'ors now in use with little or no changes or may be constructed on and operated in conjunction with new concentrators to increase the extraction and j reduce the cost of operation.

I attain these objects by attaching to concentrating vanners the mechanism illustrated in the accompanying drawings.

Figure 1 represents a view of the invention disconnected from' the concentrating vanner' to which it is to be attached, parts cut away.

Fig. 2 represents the invention in its general position as it is attached to any concentrating vanner, but the iron spool, 36, in this drawing, is shown as it is attached to the main driving shaft, 51 (immediately in front of the front eccentric, 52), on vanners of the Johnston type.

Fig. 3 is a longitudinal section of one of the adjusting elements.

Fig. 4 is a view in perspective of another one of the adjusting elements, parts cut away.

' Fig. 5 is a detail in perspective of one end portiony of the padded roller, parts cut away.

Fig. 6 is a View in perspective of one of the hinged bearings and coil springs, 3?).`

Fig. 7 is a longitudinal section of the oil cup and the worm, pinion, shaft and adjusting elements, the `worm being shown partly in elevation.

Fig. 8 is a vertical section-showing a portion of the vanner belt, brush, padded roller and rod, spray pipes and connected parts.

The vanner belts now in use whether having a plain, a corrugated or an indented Y surface frequently become coatedl with a hard scaly matter or with a slimy substance to such an extent that metallic values are lost, and the present invention is intended to prevent such formations, and also to thoroughly and economically clean the belt of all values and save them, after the metal,

of the values is effected by the individual and collective adjustments and the position of the brush, roller and sprays in connection with a trough and other elements as hereafter described.

For purposes of identification, the various parts of this invention, and the parts of the concentrating vanners to which it is to be attached are numbered and described as follows:

The present invention is placed horizontally over the water box 47, immediately in front of the lower part of the vanner as shown in Fig. 2, and consists of: a cylindrical brush 1, which is placed against and contacts with the vanner` belt 48, as shown in Fig. 2. lnto the ends of the brush the stub shafts 19 are fastened, and these extend outward and are mounted in the bearings 20 in the slots in the standards 16, as shown in Fig. 1.

A rod 2 is placed lengthwise of the brush 1, and near enough that the bristles strike the rod as the brush is rotated. The

Yends of the rod extend outward and through slots in the standards 16 as shown in Fig. 1.

A perforated pipe 3 is placed lengthwise of the brush 1 near the top and back of it in order that water from this pipe will spray the vanner belt 48, and wash the brush. The ends of this pipe extend outward and through slots in the standards 16 as shown in Fig. 1.

A padded roller 4 is placed lengthwise of the brush 1, below and slightly back of the brush, and so arranged as to contact with the vanner belt 48, and low enough in the water box 47 that its lower part passes through the water in the box, and is so arranged that its padded face cont-acts with the inside padded edge 6 of the discharging trough 7. In the ends of the padded roller' 4, the stub shafts 12 are fastened and extend outward and are mounted in bearings similar to the bearings 20, in slots in the standards 16 as shown in Fig. 1.

A perforated pipe 5 is placed lengthwise of the padded roller 4, in front and low enough to spray the padded roller and the inside padded edge 6 of the trough 7 at the point of their contact. The ends of this pipe extend outward and through slots in j the standards 16 as shown in Fig. 1.

Water is supplied to the pipes 3 and 5 through the main pipe 50, and the hose 38.

A discharging trough 7 is placed lengthwise of the padded roller 4, immediately below the roller and with the inside edge 6, of the trough 7 extending as close to and as far under the padded roller as is possible and still keep the bottom of the trough above the water in the boX 47.

One end of the trough 7 is slightly lower than the other end so the concentrates will readily discharge out of the spout 8,through the funnel 9, and into the launder 49. The trough 7 is fastened to the braces 57 of the vanner by the braces 1Q, and being fastened to the vanner it receives the cross motion of the vanner, which motion discharges the concentrates from the trough.

The device is mounted on the bases 15 which have longitudinally disposed grooves in their upper faces, into which grooves the standards 16 are placed, as shown in Fig. 1 These standards are adjusted in the grooves by the screws 17 rl`he brush 1, the padded roller 4, the pipes 3 and 5, and the rod 2 are mounted in slots in the standards 16, and are adjusted in relation to each other and to the vanner belt 48 by the adjusting screws 21.

The bases 15 are vertically adjusted by the screw legs 22.

To accommodate these adjusting devices cuts are made in the ends of the water box 47, over which cuts are placed the water Shields 11 to prevent water slopping out.

Power to operate the brush 1 and padded roller 4 is secured by attaching the spool 3G to apower shaft of the vanner. The belt 34 is placed around this spool, and passes around the pulley 35, which pulley fastens to and rotates the shaft 32, which shaft is mounted in the hinged bearings 31. The coil springs 33 take up any slack in the belt 34 and automatically adjust any variation in the mechanism.

The worm 27 is secured on the shaft 32, and is rotated thereby. This worm 27 engages with the wheel 23 which is fastened on the shaft 12 of the padded roller and rotates it in the opposite direction from that in which the vanner belt 48- is moving at its point of contact with the padded roller.

The adjustable driving rod 25 connects the wheels 23 and 24, and imparts the motion of the wheel 23 to the wheel 24, and this wheel is fastened on the shaft 19 of the brush 1, and said brush is thereby rotated in the opposite direction from that in which the vanner belt 48 is moving at its point of contact with the brush.

The adjusting screw 28 regulates the position of the worm 27 to the wheel 23, and the worm is turned in the oil cup 29.

The operation of my invention is as follows:

When the vanner is in operation power is applied through the spool 36 around which the belt 34 is placed, and this belt passes around the pulley 35 which is fastened on the shaft 32. As this shaft rotates the worm 27 imparts motion through the wheel 23 to the shaft 12 of the padded roller 4, and the roller is made to rotate in the opposite direction to the travel of the vanner belt 48 where the two contact.

Through the drive rod 25 propelling the wheel 24 the brush is also made to rotate in the opposite direction to the travel of the said belt 48 where the two contact.

The water flowing through the pipe 3 will fall as a spray on the vannerV belt 48 and cylindrical brush 1 at their point of contact and the mineral particlesy will be caught by the bristles of the brush and will be carried forward and away from the said belt and as the bristles of the brush are brought in contact with the rod 2, the mineral particles will be rubbed and washed from the brush and fall into the trough 7 Any matter that may remain on the belt 48 after it passes the brush 1 will be scraped from the face of the beltvby the padded roller 4 as'it rotates in the opposite direction to the travel of the said belt, and be carried by the roller and be scraped from the face thereof by the curved up padded edge 6 of the trough 7, and the mineral particles will be discharged by said trough through the spout 8 and funnel 9 into the launder 49. A

To make the said mineralparticles leave the face of the said roller more easily,`water is supplied through the pipe`5` in the form of spray on the points of contact between theroller face and the `padded edge 6 of the trough 7. The facel of the roller 4 is also subjected to washing in the water boi; 47 by touching the water therein. l

The said vanner belt 48 is given a lateral or cross lmotion as well as the longitudinal travel, which movements aid in the action of my attachments in cleaning the said belt of concentrates and in keeping the belt in condition to effect complete concentration. 'n

The discharge trough 7 being fastened to the braces 57 of the vanner receives the lateral motion of the vanner which forces the concentrates out of the trough, through the funnel 9, and into the launder 49, and scrapes from the padded roller'any mineral particles adhering thereto and deposits them in the trough.

By these operations the vanner belt is kept clean and in a condition to handle its greatest tonnage; to effect the greatest saving of values; the labor of handling the concentrates is saved; and the use of water is reduced to a minimum.

Having thus described my invention I desire to secure by Letters Patent and claim :-v
